An apparatus for attaching a label to an outer surface of a package is disclosed. Label is printed by a printer onto a label web, the label is separated from the web, and tacked to the wrap of the package. The label printed according to the invention is introduced onto a suction plate, which is arranged on an end of a pivoted swing arm, with a printed side of the label facing the suction plate so that an rim of the label web extends over a pressure roller. Vacuum is applied to the suction plate in order to hold the label, the label is separated from the label web by a shear device and an adhesive precoat is applied on an unprinted side of the label. The package is moved, and the pivoted swing arm is rotated against the package by an actuator so that one edge of the label is brought into an adhering contact with the outer surface of the package by the line pressure exerted by the pressure roller, whereby the label is attached by its tacky surface to the surface of the package in a nip formed between the pressure roller and the package while the movement of the package rotates the pressure roller. |
